TRANSPORT.

Application filed. June 7, 1922. Serial No. 566,488.

To all 10/ 20222 it may concern. Be it known that 1, Arm Tinon'rius, a citizen of the Empire of Germany, and residing at Kiel, Germany, have invented a new and litnproved Transport, of which the following is a specification.

This invention relates to the construction of seagoiug vessels adapted to enclose other smaller craft and the water necessary to float the smaller vessels so that barges, canal boats and other light draft cargo carriers which are not adapted for trailic on the great lakes, the oceans and other bodies of water subject to violent storms, may be safely brought from the inland rivers and canals for which they were designed, across too dangerous to be normally attempted, to points where cargoes may be obtained and discharged.

A large amount of freight originating in cities bordering on Lake Erie and the rivers emptying into this lake is loaded onto steamers to be carried to Buffalo, there unloaded onto doehs and reloaded into canal boats for cz'irriage to New York city and the -neigh'- boring ports. The cost of unloading and reloading at Buffalo of such manufactures as automobiles, heavy machinery and other articles diflicult to handle is so great that shippers are often compelled to use the more expensive railroads so as to avoid this cost and the danger of this freight being damaged by such handling.

In the accompanying drawing, Fig. 1 is a central longitudinal section of a transport and of acanal boat enclosed thereby. Fig. 2 is a plan thereof. 3 is a section on the line 33 of Fig. 1. ig. A is a detail of mechanism for operating a bracing door.

Similar reference characters refer to like parts throughout the several views.

The transport 1 is shown formed with a bow of ordinary construction and with water compartments or ballast tanks 3 so that it may be properly trimmed. A central chamber 4 is provided between the side walls 5 to receive the canal boat or barge 6, the stern of the transport being open to permit the entrance of the boat 6. A heavy door or gate 7 is preferably mounted on pivots 8 near its lower edge and may be swung down to horizontal position to permit the entrance of the boat 6. After the boat 6 is within the chamber l, this door is swung up to vertical position, bracing chains .9 being provided if desired to assist in resisting the blows of a following sea.

The bottom '10 between the walls 5 is of ffi tl t l't -t" t su -cien ceptn 0 rent e1 no ianspoi sea worthy and may be of any desired construction. The transport may be provided with screws 11 and rudders 12, although the The walls 5 assists transported in a floating dry dock during heavy weather. But when the greater portion of the dead weight is waterborne, the stresses of the load on the various parts of the boat are resisted in practically the same manner as when the boat is floating in still water, even when the transport is pitching and rolling in'a heavy sea. This is provided for by the doors 15, pivoted at their outer vertical edges in recesses 16 in the side walls 5 of the transport and these doors may b supplied with segmental rack bars 17 which engage pinions 18 on the shafts 19. These shafts may be turned in any desired manner, hand wheels 20 being shown, and when forced against the boat 6 may be held in that position by locking pins 21 that engage the teeth of pinions 18 or in any other desired manner.

These doors 15 not only prevent lateral movement of the boat 6 but they also prevent the water within the chamber from rushing forward and then aft when the transport pitches in a heavy sea. Such movements might otherwise carry all the water from one end of the chamber 4: to the other andthus drop the weight of either end of the boat 6 onto the transport, thus endangering theboat 6 which is such stresses.

When not employed to carry boats from port to port, the transport may be used as a floating dry-dock to permit repairs of the smaller craft.

probably unfitted for The construction of the transport and its proportions may be varied by naval architects without departing from the spirit of my invention as set forth in the following claims.

I claim v 1. A transport having a central chamber, a canal boat or barge in said chamber, water in said chamber to carry a portion of the weight of the enclosed boat, and means adapted to engage the sides of the boat to restrain the water within the chamber from rushing forward and back.

2. A transport having side walls connected by a bottom and a bow structure, which side walls enclose a chamber to receive a canal boat or barge, and water to float the boat, doors pivoted to said side walls to engage the boat to prevent lateral movement thereof within the chamber and to prevent the water therein from rushing forward and aft, and a gate to close the opening between said side walls at the stern of the transport.

i. A transportrhaving side walls connected by a bottom and a bow structure, which side walls enclose a chamber to receive a eanalboat or barge and waterto float the boat, doors pivoted to said side walls to engage the boat to prevent lateral movement thereo't within the chamber and to prevent the .vater therein from rushing forward and aft, and a gate to close the opening between said side walls at the stern of the transport, said gate being pivoted along its lower edge.

A. transporthaving side walls connected by a bottom and a bow structure, which side walls enclose a chamber to receive a canal boat or barge and water to float the boat, means pivoted to said side walls to engage the boat to prevent lateral movement
